PowerSync Docs

PowerSync keeps in-app SQLite synced with your backend so apps update across users and devices in real time, respond instantly, and continue working offline.

PowerSync is made up of the PowerSync Service and a set of client SDKs. The PowerSync Service replicates data from your backend database, partitions it based on what data each user should receive, and streams real-time updates to clients through the PowerSync client SDK.
